How can I combine backup from 2014, for example, with current database?

[Geneva1867]

I cannot find information on this subject anywhere on DejaOffice or the forum. Please point me to a source, if there is one.
I discovered that I can extend the history for past calendar days to sync, on PC CRM, to 34463 days. Recently, I needed this history and was dismayed to find my history was less than a year, so was in a pickle.
How can I add the missing history? Presumably, I can import old backups, but I am afraid of losing my current calendar, contacts, etc. that were added since the old backup was created. Tech support told me how to import the Android database from 2014 but did not specify if I would lose all my new information.
How can I combine or sync older databases with my current database? I am syncing between DejaOffice PC CRM Standalone (on Windows 11) and an Android phone (version 16).

Geneva,

Are the past records on the PC or on the Android still?

I have both types of backups with various dates: clusb (Android) and auto-backups on the PC.

Thank you, Thomas, for helping out!
For anyone in the same boat, I got two questions answered: upload old calendar events using a csv file and they will be new entries (won't update old/current ones). I would much rather have duplicate old(er) records than none, so i am thrilled with this solution.

These are the instructions: You can directly import the csv file on the PC in to the DejaOffice PC CRM:

1. Open DejaOffice PC CRM.
2. Select Calendar Day View.
3. In the top toolbar select 3 bars on the right and change the view to Grid. (Calendar Day View will change to List first, repeat this once more to change to Grid).
4. Select the Import icon on the toolbar.
5. Navigate to your newly formatted CSV file and select it to Import.

Note: CSV Records are imported as new records and do not update existing records.
